Abstract

An individual configuration contains at least a first structure and a second structure, which are aligned with respect to each other. A position sensing device that senses a relative position of the first structure with respect to the second structure, in order to establish that a manipulation has been performed on the configuration, is provided.

Claims

1. An individual configuration, comprising:

a construction having a first structure and a second structure aligned with respect to said first structure; and

a position sensing device for sensing a relative position between said first structure and said second structure.

2. The individual configuration according to claim 1, further comprising a position storing device for storing information on the relative position between said first structure and said second structure and connected to said position sensing device.

3. The individual configuration according to claim 2, wherein said position sensing device has a comparison device for comparing the information stored in said position storing device with a sensed relative position.

4. The individual configuration according to claim 1, wherein said first structure and said second structure are respectively formed by electrically conducting contacts touching in a partially overlapping manner.

5. The individual configuration according to claim 4, wherein said electrically conducting contacts forming said first structure have a smaller surface area than said electrically conducting contacts forming said second structure.

6. The individual configuration according to claim 5, wherein the information on the relative position is determined by a number of said electrically conducting contacts of said first structure touching an electrically conducting contact forming said second structure.

7. The individual configuration according to claim 4, wherein:

said electrically conducting contacts of said first structure, lie in a row, and are spaced apart from one another by a first distance; and

said electrically conducting contacts of said second structure, lie in a row, and are spaced apart from one another by a second distance and the first distance and the second distance are different.

8. The individual configuration according to claim 1, further comprising a MOS transistor having a buried channel and a gate, said first structure forming said buried channel of said MOS transistor, and said second structure forming said gate of said MOS transistor.

9. The individual configuration according to claim 8, wherein the information on the relative position is a deviation from a predetermined position.
